Guide to Paying LBTT: Methods, Deadlines, and Penalties Explained

Paying LBTT after an online return

After submitting an online LBTT return, you must also pay the tax correctly and on time. Use the exact Revenue Scotland transaction reference shown on submission, pay the exact rounded tax amount, and make sure the money reaches Revenue Scotland by the filing date to avoid interest and possible penalties.

• Quote the full Revenue Scotland transaction reference exactly as shown, and do not add any other words or numbers.
• Pay the exact rounded tax amount on the submitted return, as a separate payment for each return or penalty.
• Payment can be made by bank transfer, including BACS, CHAPS and Faster Payments; Direct Debit is available for some SETS agents if set up in advance.
• The tax is due on the earlier of the return submission date and the filing date, and the funds must reach Revenue Scotland by the filing date if time is short.
• Late payment can lead to interest and possibly penalties, while late filing can also trigger penalties.
• Registers of Scotland fees must be paid separately, and overpayments may not be refunded automatically if they are under £100.

How to pay LBTT after submitting an online return

This page explains how payment of Land and Buildings Transaction Tax (LBTT) works when you file online with Revenue Scotland. The key practical point is that payment must be linked to the correct transaction using the exact Revenue Scotland reference, and the tax must reach Revenue Scotland by the filing date to avoid interest and possible penalties.

What this rule is about

LBTT is not fully dealt with just by submitting the return. The tax also has to be paid correctly and on time. Revenue Scotland’s guidance focuses on the payment mechanics for online returns: what reference to use, which payment methods are available, when payment is due, and what happens if payment is late or if too much is paid.

This matters because a payment can be delayed, misallocated, or treated as unpaid if the wrong reference is used, if the amount does not match the return, or if payment is made too close to the deadline without allowing for clearance time.

What the official source says

When an online LBTT return is submitted, Revenue Scotland displays a unique tax reference for that transaction. For returns submitted on or after 24 July 2019, this is a 13-character reference beginning with “RS”, followed by 7 numbers and ending with 4 letters. For returns submitted before that date, the reference is a 9-character number beginning with “RS” followed by 7 numbers.

Revenue Scotland says that the full transaction reference, and only that reference, must be quoted when making payment or contacting them about the transaction. The payment should exactly match the rounded total tax payable shown in the submitted return.

The guidance allows payment by bank transfer, including BACS, CHAPS and Faster Payments, to Revenue Scotland’s specified bank account. A separate payment must be made for each tax return or penalty.

Revenue Scotland also offers Direct Debit for agents who are registered users of SETS, but this must be set up in advance and may take up to 10 days.

On timing, the guidance says the tax is due on the earlier of the date the return is submitted and the filing date for the return. The latest payment date must be a banking day. Revenue Scotland allows five days for payment to clear as part of “Arrangement Satisfactory”, but if the return is submitted close to the filing date, full payment must reach Revenue Scotland no later than the filing date.

Interest is charged on tax that remains unpaid after the filing date. Late filing can lead to a penalty. Late payment can lead to interest and may also lead to a penalty depending on how late the payment is.

The guidance also makes clear that registration payments due to Registers of Scotland are separate and must not be paid to Revenue Scotland.

If there is an overpayment, Revenue Scotland says it will make every effort to refund it where the amount is £100 or more. If the overpayment is under £100 and Revenue Scotland does not hold repayment details, a refund will only be made if requested. Unclaimed overpayments are paid into the Scottish Consolidated Fund.

What this means in practice

In practice, paying LBTT correctly involves more than simply sending money to the right bank account.

First, the transaction must be identified properly. Revenue Scotland relies on the unique LBTT reference generated when the online return is submitted. If a different reference is used, or if extra wording is added, there is a real risk that the payment will not be matched to the return.

Second, the amount paid should match the tax shown on the submitted return. The guidance specifically says the payment should exactly match the rounded total tax payable. If the amount differs, that may create reconciliation problems and could leave an apparent underpayment.

Third, each liability is treated separately. If there are several returns, or a return and a penalty, separate payments should be made for each one. A single combined payment is not what the guidance expects.

Fourth, timing matters. Even though Revenue Scotland allows five days for payment to clear in the context of Arrangement Satisfactory, that is not a safe reason to leave payment until the last moment. The guidance is clear that if the return is submitted close to the filing date, the money must actually reach Revenue Scotland by the filing date.

Finally, do not confuse tax payment with registration fees. Money due to Registers of Scotland for registration must be paid separately to Registers of Scotland, not to Revenue Scotland.

How to analyse it

If you are checking whether LBTT payment has been dealt with properly, these are the main questions to ask:

• Has the online return been submitted?
• Was the unique Revenue Scotland transaction reference captured accurately from the submission screen?
• Is the payment being made to Revenue Scotland rather than to another body?
• Does the payment reference contain the exact LBTT reference and nothing else?
• Does the amount paid exactly match the rounded tax payable on the return?
• If there is more than one return or any penalty, has each one been paid separately?
• Will the money reach Revenue Scotland by the filing date, taking account of bank processing times and banking days?
• If using Direct Debit, has it been set up early enough?
• Have any separate registration fees been paid to Registers of Scotland instead of being mixed into the tax payment?
• If too much was paid, does Revenue Scotland hold the repayment details, especially where the overpayment is under £100?

This framework is useful because most payment problems arise from one of three issues: wrong reference, wrong amount, or payment arriving too late.

Example

A buyer’s agent submits an online LBTT return and receives a 13-character reference beginning with “RS”. The return shows a rounded tax liability of £8,450. The agent should make a payment of exactly £8,450 to Revenue Scotland’s bank account and use only that transaction reference as the payment reference.

If the same agent also needs to pay a penalty on another matter, that should not be added into the same bank transfer. It should be paid separately using the unique reference shown on the penalty notice.

If the return is submitted shortly before the filing date, the agent should not assume that starting a payment is enough. The money must reach Revenue Scotland by the filing date to avoid interest on unpaid tax.

Why this can be difficult in practice

The official guidance is operational rather than analytical, so some practical points can catch people out.

One issue is the distinction between the date a payment is initiated and the date it clears. The guidance refers both to due dates and to Revenue Scotland allowing five days for payment to clear as part of Arrangement Satisfactory. But it also says that if the return is submitted close to the filing date, full payment must reach Revenue Scotland no later than the filing date. In practice, that means leaving payment until late in the process is risky.

Another difficulty is that parties in property transactions often deal with several payments at once: LBTT, registration dues, professional fees, and sometimes penalties or interest. The guidance requires these to be kept separate. Mixing them can create administrative problems even where the total cash sent is enough overall.

A further point is that the payment reference rules are strict. The guidance says to use the full unique reference, and only that reference. That suggests Revenue Scotland expects exact matching rather than approximate identification.

Overpayments can also be overlooked. Revenue Scotland says it will make every effort to refund overpayments of £100 or more, but smaller amounts may not be refunded automatically unless repayment details are held or a request is made. That means small balances can remain unresolved unless someone checks them.

Key takeaways

• Use the exact Revenue Scotland transaction reference shown when the online LBTT return is submitted, and use only that reference.
• Pay the exact rounded tax amount to Revenue Scotland, separately from any Registers of Scotland registration payment and separately from any penalty.
• Make sure the money reaches Revenue Scotland by the filing date, because late payment can trigger interest and possibly penalties.
